In recent years, railway infrastructures and systems have played a significant role as a highly
efficient transportation mode to meet the growing demand in transporting both cargo and …

To date, the application of self-sensing or other structural health monitoring (SHM)
technologies in railway sleepers is limited. Development and deployment of smart sleepers …

Photoacoustic (PA) imaging has been widely used in biomedical research and preclinical
studies during the past two decades. It has also been explored for nondestructive testing …

Non-destructive monitoring methods and continuous monitoring systems based on them are
crucial elements of modern systems for the management and maintenance of assets which …

The ultrasound technique is a well-known non-destructive and efficient testing method for on-
line corrosion monitoring. Wall thickness loss rate is the major parameter that defines the …

An all-optical ultrasound sensing system based on photoacoustic principle is developed to
monitor and investigate the initiation of early stage steel rebar corrosion in real time. The …

Fiber-tip air cavity sealed by cutting-free inwardly concave silica diaphragm cascaded to
fiber Bragg grating for gas pressure sensing is proposed. According to the measured …

The work is devoted to an overview of the current state of optoacoustic fiber-optic ultrasonic
transducers based on thermoelastic effect and fiber-optic interference receivers, its scope …

Optical fiber photoacoustic (PA) probe is considered to have great prospects in high
resolution invasive imaging due to the advantages of flexible, miniaturized broadband …

This paper presents the design, fabrication and testing of a single-mode fiber optic
ultrasound transducer. This transducer can work as an ultrasound generator and a receiver …
